If you are a company that collects and processes data from EU residents, you are likely a data controller and would be required to comply with the new EU General Data Protection Regulation (GDPR) that came into effect on May 25th, 2018.
The GDPR was enacted to strengthen the privacy and control EU residents have over their personal data. Part of that is achieved by extending certain data protection requirements that previously were only for data controllers to data processors as well.
As a data controller, you are now required to work only with GDPR-compliant data processors. Because Rollbar processes data on your behalf, we are a data processor to you and are directly obligated to comply with this regulation.
Rollbar treats all data received as potentially containing personal data, and only processes data that you provide to us for the purpose of monitoring errors in your applications.
